2013 Mazda 5 Sport 110,000 miles. No warning lights no codes thrown.
Wife let the brakes get pretty low on fluid, barely any (but a little) visible in the reservoir. Brakes got spongey, lots of travel, loud brake booster. I topped it off and the situation got about 50% better.
Front pads were low, just about 2 MM left so I replaced them. I've done them once before without complications. Did the same steps, and did not bleed at this time.
Took the car out, brakes were really nice and firm and responsive, almost like when new. Gave a couple firm stops from 40 to 0 (not panic stops, just firm, no ABS shudder felt) and the brake instantly became very spongey and unresponsive. They still kinda-work and bottom after 2.5-3 inches travel.
Brought it home and up on the stands, bled from back to front and then bled zig-zag some people on a few forums suggested. At right rear I got a bit of foamy bubbles the first bleed, but that's all I ever got. Bleeding gave maybe a 20% improvement.
I am stumped. Air in the ABS module or a valve stuck open in there? Maybe I just need a power bleed? I know many mechanics would be glad to sell me all the relevant parts, needed or not.
